To all 'whom it may concern.'

Be it known that we, HumoaY P. INGBAM and HARRY I. INoaAM, citizens of the United States, residing at De Ridder, in the parish of Beauregard, State of Louisiana, have invented a new and useful Oil-Burner.

lhis invention relates to an improvement in oil burners.

The primary object of the present invention is to provide means for thoroughly heating the oil and generating gas before the same is supplied to the burner.

With the foregoing and other objects in view which will appear as the description proceeds, the invention resides in the comination and arrangement of parts and in the details of construction hereinafter described and claimed, it being understood that changes in the precise embodiment of the invention herein disclosed can be made within the scope of what is claimed without de arting from the s irit of the invention.

n the drawin igure 1 is an elevation of the comp ete apparatus, the burner and oil heater being partly in section. Fig. 2 is a section on the ne 2-2 of Fi 1.

In the drawings, 10 designates t e tank or oil receptacle which is partially filled with oil. Air is forced in said tank by means of the ump, 11 to create suflicient pressure to feed the oil to the burner. The pum is connected to the tank by the pipe 12, tie tank being rovided with a valve 14 which is set to maintain a predetermined air pressure within the tank. The supply pipe l is connected to the tank at a point adjacent to its base, a valve 16 being positioned between the tank and the burner.

An auxiliary pipe 18 leads from the upper portion of the tank to the interme iate portion of the horizontally disposed ipe 15, there being a valve 18 interposed in t e pipe 17. The pipe communicates with a vertically disposed pipe 19, the pipe 19 communicatng with a needle valve 20 which in turn, communicates with a horizontall isposed tube 21. This tube 21 is arrange concentrically within the cylinder 22, the oil passing to the tube 21 and out throu h the pen end of said tube into the c lin er 22.

he connection at 24 is dispose centrally of the casing 22 with the vertically disposed pipe 25 supporting the burner 26 which is disposed a ove a an 27, so the heated oil gasifying passes t ough the pipe 25 to the burner 26.

The many advantages in a device of this character will be clearly ap arent as it will be noted that the oil supply ma be positioned at a point .remote from t e burner, and the oil supplied to the burner the oil being heated and gasiiied before t e same passes to said burner. Attention is also called to the fact that the entire construction is such as ma be easily and economi-- call manufacture the various parts being rea ly assembled.

Assumin that the valve 18 is open and that there 1s no air pressure in the tank 10, the liquid will stand at the same level in the tank 10 and pipe 17. Upon closing the valve 18 and pumping air into the tank 10, the pressure will cause the liquid in the pi e 17 to rise to a higher level than in the tan compressing the air between it and the valve 18. But the air pressure in the portion of the pipe 17 to the right of the valve 18 is always less than that on the other side of the valve, as the air in the tank 10 must sustain a column of liquid in the pipe 17 of reater height than that in the tank 10.

`hus, upon openin the valve 18, the teinporary surging bac and forth of the liquid in the tank 10 and pipe 17 in the attempt to reach equilibrium will cause sufficient decrease in pressure at the valve 20 to allow back pressure from the cylinder 22 to dislodge an obstruction in the valve 20. To put the device again in condition to operate as described, it will be necessary to release the air under ressuie close the valve 18, and again supp y air under pressure to the tank 10, thereby agliliin securin columns of liquid of unequal eight in t e tank and pi e 17.

IilVhat is claimed is: In a device of the class described, a fluidcontaining tank; a main pipe entering the tank adjacent the bottom of the tank; an auxiliary pipe forming a communication between the main pipe and the upper portion of the tank; an air pump discharging into the tank; a cut o valve'in the aux as our own, we have hereto axed our sigiliary ipe and located adjacent the tank natures in the presence of two witnesses. 10
